Crontab Change Macro

The crontab_change_alarms_macros.cfg is a script macro to report crontab changes.

crontab_change(u)
 
        init
                status =piktstatus
                level =piktlevel
                task "Report changes in (u) crontabs"
                input proc "if [ -e =hstdir/log/(u).crontab.bak ];
                            then =diff =hstdir/log/(u).crontab.bak
                                       =hstdir/log/(u).crontab 2>/dev/null;
                            else =cat =hstdir/log/(u).crontab 2>/dev/null;
                            fi"
        begin
                doexec wait "=crontab -u (u) -l > =hstdir/log/(u).crontab"

        rule
                output mail $inlin

        end
                doexec wait $lower("=mv =hstdir/log/(u).crontab
                                        =hstdir/log/(u).crontab.bak")
                quit

You might invoke the =crontab_change() macro in your alarms.cfg file thusly:

///////////////////////////////////////////////////////////////////////////////
//
// logs_system_alarms.cfg
//
///////////////////////////////////////////////////////////////////////////////
 
RootCrontabChange
 
        =crontab_change(root)
 
///////////////////////////////////////////////////////////////////////////////
 
ACMECrontabChange
 
        =crontab_change(acme)
 
///////////////////////////////////////////////////////////////////////////////

Output from this script might look like, for example:

NOTICE:
    ACMECrontabChange
        Report changes in acme crontabs
        2c2
        < # (/tmp/crontab.XXXXa3sFgY installed on Wed Sep  5 10:09:46 2007)
        ---
        > # (/tmp/crontab.XXXXZP0hLb installed on Fri Sep  7 15:53:49 2007)

        < 16 3 * * 1-5 /usr/local/acme/bin/task.prod/startTaskProd_part7.sh
